PROSTHETIC HEART VALVES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Ebstein anomaly involves the downward displacement of 1, 2, or 3 tricuspid valve leaflets into the RV.
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Ebstein anomaly is a rare congenital abnormality involving the tricuspid valve and the right ventricle. Ebstein anomaly occurs when an apical displacement of the tricuspid valve with tethering of leaflet attachments.

Detailed explanation-2: -Ebstein’s anomaly is a defect of the tricuspid valve. The tricuspid valve separates the right atrium (the chamber that receives blood from the body) from the right ventricle (the chamber that pumps blood to the lungs). In Ebstein’s anomaly, two leaflets of the tricuspid valve are not in the right place.

Detailed explanation-3: -Ebstein anomaly is a rare heart defect that’s present at birth (congenital). In this condition, your tricuspid valve is in the wrong position and the valve’s flaps (leaflets) are malformed. As a result, the valve does not work properly. Blood might leak back through the valve, making your heart work less efficiently.

Detailed explanation-4: -Abstract An indexed offset distance of the tricuspid septal leaflet ⩾8 mm/m2 is a quantitative criterion for the diagnosis of Ebstein’s anomaly.
